Ecology, silviculture, and management of Black Hills ponderosa pine

Publications Posted on: June 22, 2020
This paper presents a broad-based synthesis of the general ecology of the ponderosa pine ecosystem in the Black Hills. This synthesis contains information and results of research on ponderosa pine from numerous sources within the Black Hills ecosystem.

Mapping multiple insect outbreaks across large regions annually using Landsat time series data

Publications Posted on: June 17, 2020
Forest insect outbreaks have caused and will continue to cause extensive tree mortality worldwide, affecting ecosystem services provided by forests. Remote sensing is an effective tool for detecting and mapping tree mortality caused by forest insect outbreaks. In this study, we map insect-caused tree mortality across three coniferous forests in the Western United States for the years 1984 to 2018.

The ecology, history, ecohydrology, and management of pinyon and juniper woodlands in the Great Basin and Northern Colorado Plateau of the western United States

Publications Posted on: January 30, 2020
This synthesis reviews current knowledge of pinyon and juniper ecosystems, in both persistent and newly expanded woodlands, for managers, researchers, and the interested public. We draw from a large volume of research papers to centralize information on these semiarid woodlands. The first section includes a general description of both the Great Basin and northern Colorado Plateau.

Rio Grande National Forest: Insect and Disease Bibliography

Climate change and selected forest insect and pathogens in the Rio Grande National Forest

Documents and Media Posted on: April 23, 2019
Naturally, many insects and pathogens occur in the Rio Grande National Forest (RGNF) but only a few are relevant in terms of tree mortality and their contribution to forest structure and composition. In this document, Research Entomologist Jose Negron briefly comments on the effect of climate change on selected insects and pathogens. Document Type: Other Documents

Environmental, structural, and disturbance influences over forest floor components in interior Douglas-fir forests of the Intermountain West, USA

Publications Posted on: August 21, 2018
Downed woody material (DWM) is a key component in forest ecosystems with age, structure, and disturbance described as primary factors that influence DWM dynamics. In particular, much emphasis is placed on large coarse woody debris (CWD).

Growth and survival before and after a mountain pine beetle outbreak in a ponderosa pine genetic trial

Datasets Posted on: March 15, 2018
This data package contains data used for the publication "An insect outbreak shifts the direction of selection from fast to slow growth rates in the long-lived conifer Pinus ponderosa" (de la Mata et al. 2017). The study includes measurements from 204 half-sibling families planted in a common garden experiment planted in 1974 and last measured in 2013.

Insects associated with fire-injured ponderosa pine

Science Spotlights Posted on: August 24, 2016
Rocky Mountain Research Station scientists are looking at tools aimed to respond to insect infestations after a fire occurs, particularly around large-scale conifer forests. Different types of fire injury and tree characteristics, such as the extent of bark damage, crown injury, and tree size were correlated to infestations by different bark beetles and wood-boring insects. Some of the insects occured jointly and were associated with both live and dead trees.

Rocky Mountain Research Station: 2003 Research Accomplishments

Publications Posted on: June 30, 2016
The Rocky Mountain Research Station is one of six regional units that make up the USDA Forest Service Research and Development organization - the most extensive natural resources research organization in the world. We maintain 12 field laboratories throughout a 14-state territory encompassing the Great Basin, Southwest, Rocky Mountains and parts of the Great Plains.
